Irregular verbs

Grammar Lesson

You have already learned some irregular verbs. The verbs ser (from lesson 3), estar (from lesson 4) and tener (from lesson 6) are all irregular verbs. You also learned verbs that are irregular only in the yo form in lesson 14. In this lesson you will learn more irregular verbs including the verb ir (to go), verbs that have stems that change in the present tense and verbs whose spelling changes in certain forms. There are a lot of new verbs on this page, and you can't be expected to memorize them all. Focus on getting familiar with the types of stem changes. You will be re-introduced to the verbs again as they are used in futures lessons.
